LETTER OF TRANSMITTAL. 



Department of the Interior, 
United States Geological Survey, 

Hydrographic Branch, 
Washington, D. C, May 5, 1904. 
Sir: I have the honor to transmit herewith a manuscript by John 
C. Hoyt and Robert H. Anderson, relating to the hydrography of the 
Susquehanna River drainage basin, and recommend its publication 
in the series of Water-Supply and Irrigation Papers. 

In this paper has been brought together, in such form as to be of 
use to both the general and the engineering public, all the available 
hydrographic information in regard to this important area. 

It is intended that this paper shall be published in sequence with 
another (No. 108) entitled "Quality of Water in the Susquehanna 
River Drainage Basin, by Marshall Ora Leighton, with an Introduc- 
tory Chapter on Phj^siographic Features, by George Buell Hollister." 
The combination of the two papers will make available a large 
amount of valuable information with reference to the resources of 
this important river system. 
Very respectfully, 

F. H. Newell, Chief Engineer. 
Hon. Charles D. Walcott, 

Director United States Geological Survey.

HYDROGRAPHY OF THE SUSQUEHAMA RIYER BASIN, 



By John C. Hoyt and Robeet H. Anderson. 



IlS^TRODUCTIO?^. 

A detailed study of the hydrographic features of the Susquehanna 
River drainage basin has revealed the existence of a large amount of 
interesting data. These, however, are widely distributed in various 
publications and manuscripts which are in most cases inaccessible. 
This paper has been prepared to meet the constant demand for this 
information from both the general and the engineering public. The 
general deductions are intended to give the general reader a compre- 
hensive review of the principal conditions which exist in this area, 
while the base data have been given for the use of the engineer, so 
that he maj' make his own deductions and have sufficient data for 
estimates in hydraulic investigations. 

ACKNOWIiEDGME:N^TS. 

The records and reports of the United States Geological Survey 
have been the chief sources from which the data on flow have been 
obtained. These records have been carefully revised and in many 
cases recomputed. New rating tables based on all the discharge 
measurements to date have been prepared and the tables of estimated 
discharge have been revised to agree with these rating tables. These 
recomputations will account for the differences between the figures 
herein presented and many of those in the previous reports, as the 
latter were prepared from year to year with such information as was 
available. Special acknowledgment is due to E. G. Paul, resident 
hydrographer for Pennsylvania, who established the gaging stations 
and under whose direction the discharge measurements in this State 
have been made. The stations in New York were established and 
have been maintained under the direction of R. E. Horton, resident 
hydrographer for that State. 

The base data from which the precipitation tables have been pre- 
pared were taken from the published reports of the United States 
Weather Bureau. 



lO HYDEOGKAPHY OF SUSQUEHANNA BASIN. [no. 109. 

The tables showing the utilized horsepower in 1900 are from manu- 
script schedules furnished by the manufactures division of the 
Twelfth Census. 

In the preparation of descriptive portions of the paper Vol. XVI 
of the reports of the Tenth Census (Water Powers, Part I), Rogers's 
Geology of Pennsylvania, and the Army Engineers' reports have been 
largel}^ drawn upon. 

The annual reports and original records of the Chief of Engineers, 
United States Army, have furnished valuable information in regard 
to declivity, and the profiles herewith given are largely based upon 
them. 

The data for McCalls Ferry have been furnished through the kind- 
ness of Dr. Gary T. Hutchinson, of New York City, who is interested 
in the power development at that point and had charge of extensive 
surveys and studies there in 1902 and 1903. Special mention is due 
Boyd Ehle and R. H. Anderson, who established and carried on the 
measurements at the McCalls Ferry gaging station. 

Acknowledgment is also due to Frank H. Brundage, H. J. Saunders, 
L. R. Stockman, and other members of the hydro-computing section 
of the United States Geological Survej^ for assistance given in the 
computations and in other work connected with the preparation of 
the many tables. 

DESCRIPTIOIS^ OF DRAINAGE AREA. 

■ GENERAL FEATURES. 

The Susquehanna River basin is the largest and most important 
drainage area commercially in the^North Atlantic States, although it 
is not the most important as regards water power, The headwaters 
of this river system are on the elevated plateau which separates the 
waters which flow south and east into the Atlantic streams from those 
flowing north and west into the Mississippi, St. Lawrence, and Great 
Lakes. 

Geologically, this watershed lies in four physiographic divisions: 
the Allegheny Plateau, the Allegheny Mountains, the Great Allegheny 
Valley, and the Piedmont Plateau. Its distribution among these 
provinces is approximately as follows: Allegheny Plateau, 56 per 
cent; Allegheny Mountains, 31 per cent; Great Allegheny Valley, 6 
per cent; Piedmont Plateau, 7 per cent. 

As the physical features of the foregoing divisions and the early 
history of the formation of this basin, as well as the qualitj^ of the water, 
have been fully discussed by Messrs. G. B. Hollister and M. O. Leighton 
in Water-Supply Paper No. 108, further discussion here is omitted. 

The Susquehanna drainage basin, as shown in fig. 1, has a total area 
of 27,400 square miles. It comprises 21,060 square miles in Pennsyl- 
vania, or about 47 per cent of the area of the State; 6,080 square 
miles in New York, or 13 per cent of the area of the State; 260 square 
miles in Maryland, or about 2 per cent of the area of the State. It

SUSQUEHANNA RIVER BELOW WEST BRANCH. 

STisquehanna River is joined by the West Brancli at Sun bury, 
Nortbumberland County. Below this point the river drains an area 
of 9,230 square miles. It flows nearly south, between Northumberland, 
Dauphin, and Lancaster counties on the east and Snyder, Juniata, 
Perry, Cumberland, and York counties on the west, passing then into 
Maryland, where it flows between Cecil County on the east and Har- 
ford County on the west, and empties into Chesapeake Bay at its 
northern extremity. 

Below the mouth of the West Brancli the fall becomes more irregu- 
lar than above, and there are rapids where the stream flows over a 
rocky bottom. In the lower part of its course from Marietta to Havre 
de Grace the river occupies a deep valley, varying in width from 
a few hundred yards to more than 2 miles, and on either shore it 
is for the most part bounded by rocky bluffs surmounted by a table- 
land 100 to 500 feet above the stream. The channel is in many places 
filled with small rocky islands, some of which are cultivated. Pis. I, 
J5, and YIII show typical views of this part of the river. 

The fall of the main river is rapid. Its elevation at the mouth of 
the West Branch is about 400 feet above mean sea level at Havre de 
Grace. The distance between this point and Havre de Grace is about 
125 miles, hence the mean slope of the main river is nearly 3^ feet 
per mile. The slope is, however, extremely variable, being over 5 
feet per mile in the lower 40 miles and about 2| feet per mile in the 
upper 40 miles. The change in slope takes place as the river passes 
from the Allegheny Mountain and the AUeghenj^ Valley regions to the 
Piedmont Plateau region. 

The tables on pages 207-210 give the elevation of the river and its 
branches at various points, and Pis. XXVIII and XXIX show their 
profiles. 

This part of the river is described by Prof. H. D. Rogers as follows:'* 

Between Northiimberland and the Kittatinny Valley the river leads its through 
many striking scenes. It is studded with many little islands, most of which are 
covered with trees or bushes to the water's edge, and it is here a wide and majestic 
river, flowing alternately for long reaches across highly cultivated belts of coun- 
try and past the ends of steep and rugged mountains. Passing out from the 
mountains it traverses a beautiful country in the Kittatinny Valley, dividing 
Dauphin from Cumberland County. Quitting the limestone valley the river 
next traverses the red-shale belt, between the villages of Highspire and Bain- 
bridge, crossing a rather monotonous country, except at the Conewago Falls, or 
rapids, where numerous hard trap dikes impede its course and cause it to rush in 
wild tumult, by deep and dangerous sluices, for a long distance between black 
and jutting reefs. At Chickies Ridge, 1 mile above Columbia, the river leaves 
the smoother country and passes between a range of high and picturesque crags. 
"With two or three intermissions, caused by the softer limestone valleys which it 
next crosses, it runs the whole way thence to the vicinity of Port Deposit, or 
nearly to the Chesapeake Bay, between steep naked and half naked hillsides, rising 

<« (reol, Pennsylvania, p. 49. 



20 HYDROGRAPHY OF SUSQUEHANNA BASIN. [no. 109. 

from 300 to 400 feet above its channel. In some parts of this long reach, as at 
Washington Borough, the river is greatly dilated and is filled with rocky islands 
and projecting reefs. In other localities its rugged banks approa jh. and the river 
rushes with tremendous force, especially during freshets, through these deeper 
gorges. The traveler, who finds only a rough and very toilsome path along its 
eastern shore from Turkey Hill to Port Deposit, a distance of more than 30 miles, 
will choose to descend it by its right bank along the towpath of the canal. He 
will pass an almost unbroken succession of interesting rocky scenes, affording 
much geological instruction, and he will witness many beautiful bits of river per- 
spective, but he will find himself pent in all the way between the bold river hills. 

The principal tributary below the West Branch is the Juniata, which 
has its source in Bedford, Blair, and Somerset counties. Pa., at an ele- 
vation of about 2,000 feet above sea level. The divide between its 
waters and those of the Ohio attains in places a height of nearly 2,800 
feet. The valley of the stream is narrow and the banks are generally 
high. The stream has a number of both large and small tributaries. 
Doctor Rogers describes the -Juniata as follows : "- 

This second great tributary of the Susquehanna has two chief upper divisions, 
the Frankstown and the Raystown branches, both of which, like the main stream 
below their junction, traverse much beautiful scenery. We will trace the Franks- 
town Branch as that which is most accessible. After gathering its headwaters 
from the eastern slope and the foothills of the Allegheny Mountains it begins to 
assiTine the volume of a small river near Frankstown. Below this point it first 
passes the cove of the Lock Mountain, a curious district of conical hills, in struc- 
ture like the Muncy Hills of the West Branch. Its course is now by a wild and 
rocky gorge through the Lock or Canoe Mountain into Canoe Valley. Winding 
northeastward through this valley it next goes through Tusey Mountain into 
Hartslog Valley by an interesting curving pass of the form of the letter S. The 
mountain, which consists of two ridgesi^,4s trenched along its center for the pas- 
sage of the river, and the western ridge iSu moreover, breached at Water street by 
a lateral not3h, which gives passage to a small tributary stream and heightens 
much the pisturesqueness of the place, which is further enhanced by a great stone 
slide covering the ends of the mountain. Crossing Hartslog Valley it next trav- 
erses Warrior Ridge, passing by the Pulpit Rocks. Emerging from the Warrior 
Ridge and deflecting more toward the east it crosses the Huntingdon Valley and 
passes by the northern end or knob of Terrace Mountain or Slideling Hill , receiv- 
ing first the Raystown Branch, which nearly doubles the volume of its waters. 
Here, bending southward, it follows a picturesque gap through Stoi:e Ridge, and 
turning more eastward it presently enters the deep cleft in Jacks Mountain called 
" Jacks Narrows,"' upon the western side of which the mountain is covered with 
a great stone slide or field of naked angular blocks of sandstone, which imparts a 
most desolate aspect to the pass, especially when the forest is not in leaf. 

On emerging from Jacks Narrows the river crosses a succession of open valleys 
divided by narrow ridges until it meets the base of Blue Ridge in Sugar Valley. 
There it makes a great loop, turning in an oxbow backward till it reaches Newton 
Hamilton, where it flows with many large sinuosities longitudinally through the 
Juniata or Lewistown Valley to the deep synclinal ravine called the ' ' Long Nar- 
rows," formed by the near approach of the Blue and Shade mountains. The 
Long Narrows of the Juniata is a narrow trough between mountain ridges, deeply 
trenched on their flanks and thickly clothed with timber on their lower slopes and

at their base, and overspread nearer their snnimits with extensive sloping sheets 
of dark-gray angular blocks. The pass is 7 miles long and is one of the wildest and 
most impressive within the mountains. At the eastern end of the Long Narrows 
the river tvirns southeastward and winds between hills and valleys across the 
country to the base of the Tiiscarora Mountain, passing Mifflintown, Mexico, and 
other villages. Below New Mexico it sweeps the base of the Tuscaroi-a Mountain 
for several miles, until it turns abruptly across its eastern end a mile northwest of 
Millerstown. Below Millerstown the river crosses the Wildcat and Buffalo val- 
leys, washing the end of the Buffalo Mountain. Pursuing its course, the Juniata, 
after making two or three bends, flows through a belt of hills called the " Half- 
Fall Mountain," where, as at nearly all its passes through the larger sandstone 
ridges, it is impeded by ledges of hard strata and thrown into ripples or rapids. 
From the Half-Fall Rapids it flows between steep but low cliffs and hills for about 
4 miles farther, to its entrance into the main Susquehanna at Duncans Island, 
having followed a winding course entirely across the central zone of the Appa- 
lachian chain through a distance of nearly 200 miles. 

SUSQUEHANNA RIVER ABOVE WEST BRANCH. 

This portion of the stream and its tributaries drain an area of about 
11,140 square miles, of which 6,080 are in New York and 5,060 in 
Pennsylvania. It rises in Otsego Lake, in Otsego County, N. Y., 
which is about 7^ miles long and 1^ miles wide, and has an 
elevation of about 1,193 feet above sea level. It flows in a south- 
westerly direction through Otsego, Chenango, and Broome counties, 
N. Y., into Susquehanna County, Pa. It then flows in a westerl}^- 
northwesterly direction through this county and again enters New 
York and takes a westerly course through Broome and Tioga coun- 
ties to near the western boundary of Tioga County, where it turns 
south and enters Pennsylvania. Before leaving New York its volume 
is rapidly swelled by many large tributaries. After entering Pennsyl- 
vania the second time it flows through Bradford, Wj^oming, Luzerne, 
Columbia, Montour, and Northumberland counties to its junction with 
the West Branch, above Sunbury. 

This portion of the drainage basin is varied in character. In New 
York it is a rolling and sometimes rather broken country, forming the 
plateau bounding the mountain region on the north. The stream has 
a very uniform declivity in this part of its course and offers compara- 
tively little power. Its bed is gravel or sand, with an occasional 
rocky ledge. Its banks are moderately high, shelving, and are sub- 
ject to overflow only in extreme freshets. 

After it enters Pennsylvania it flows through the mountain regions, 
and its course is in many places tortuous as it winds along the paral- 
lel ranges of hills. In general, however, its fall is gradual, its bed 
being composed mostly of drift materials — gravel, sand, and bowl- 
ders. The banks, as in New York, are generally high and are seldom 
overflowed, although the river has an extreme rise of as much as 30 
feet. 

In this portion of the drainage area is located the great Lackawanna 
and Wyoming coal basin, and J. H. Dager reported upon this, in sub- 



^2 HYDROGRAPHY OF SlTSQtJEHANlSrA BASIN. Ixo. 109. 

stance, as follows: "• This basin extends from Nanticoke on the sonth- 
west, where the river emerges from the Coal Measures, to Carbondale 
on the northeast. It is about 50 miles in length and averages o^ miles 
in width. It is surrounded by the Allegheny Mountains, which are 
composed of the Catskill formation and rocks of the Carboniferous 
system. 

In this vicinity there are several workable seams of coal, ranging 
from 3 to 14 feet in thickness and at depths varying from nothing to 
800 feet. These seams are from 10 to 200 feet apart vertically, and 
are underlain by sandstone and fire clay. 

From the outcrop of the Coal Measures just above Pittston to the 
New York State line the country is traversed by long, narrow, parallel 
ranges of mountains whose axes are nearly at right angles to the gen- 
eral direction of the river. At bends on the convex side there rise 
from the shore abrupt cliffs from 200 to 400 feet in height, opposite 
which, with one or two exceptions, are gently sloping cultivated lands. 

Professor Rogers refers to this portion of the river as follows : * 

That portion of the Susquehanna River which flows near the northern boundary 
of the State passes from its sharp elbow, called the " Great Bend," to the mouth 
of its affluent, the Chemun;^ River, through a charming, broad valley, bounded 
by soft slopes terminating in wide, table-shaped hills. It is a fertile and very 
beautiful district, and with its westward extension, the plain of the Chemung 
River, is rapidly becoming one of the most attractive agricultural districts of 
New York. From the mouth of the Chemung River to Pittston, where the river 
suddenly tvirns at a right angle on entering the Wyoming coal field, it flows, with 
many bendings, along a deep and picturesque valley, almost identical in its fea- 
tures with that o" the corresponding st,retch of the Delaware, the main difference 
being that the bed of the valley is wider^and the hillsides confining it less moun- 
tainous. From the mouth of the Lackawanna, at Pittston, where it enters, to 
Nanticoke, where it leaves the beautiful Wyoming Valley, the scenery along the 
river is wholly different. It flows through a broad and almost perfectly level, 
smooth plain — the Wyoming and Kingston flats — composed of a deep bed of dilu- 
vium or drift. On either side of this plain rise the rolling hills of the coal basin, 
and behind these the long, gentle slopes of the high mountain barriers, which 
frame in the whole scene. At Nanticoke the river turns abruptly northward out 
of the coal basin, through its steep barrier, by a highly pictiiresque pass, and then 
sweeps again as suddenly westward to run for several miles in a closely confined 
trench batween the outer and the inner ridges of the basin. It does not, however, 
run round the western end of this, but at the ravine of the Shickshinny turns 
suddenly southward and cuts across its point, leaving a high, isolated hill of the 
coal strata on its western or right-hand side. Disengaging itself by a fine pass 
from the southern barrier of the coal basin, it passes out into an open valley and 
makes another rectangular bend, to run once more toward the west, parallel with 
the Nescopeck Mountain, which it follows to the neighborhood of Catawissa. 
Beyond this point it maintains its general course westward, somewhat south, 
parallel with the southern base of Montour Ridge, all the way to Northumber- 
land, where it is joined by its great tributary, the West Branch. In some portions 
of this long reach of the river the scenery adjoining it is uncommonly rich and 
pleasing. A remarkably fine view up the river is presented from the hills on its 
west bank, a little below the mouth of Fishing Creek.

WEST BRANCH OP SUSQUEHANNA RIVER. 

The drainage basin of the West Branch has an area of approxi- 
mately 7,030 square miles, all of which is in Pennsylvania. The 
West Branch has its sources in the mountains of Cambria County at 
an elevation of not less than 2,000 feet above sea level. It flows first 
in a northward direction, receiving some tributaries from Indiana 
County on the west, into Clearfield County. Gradually bending to 
the right, it flows northeast between Center and Clinton countieSj 
east through Clinton and Lycoming counties, and south between 
Union and Northumberland to join the main stream above Sun- 
bury, Pa. 

The watershed of this stream occupies the high table-lands of the 
north-central part of Pennsylvania. The crest of the watershed has 
an elevation of from 500 to 1,200 feet above sea level in the vicin- 
ity. of the junction of the West Branch and the main stream, in- 
creasing to about 2,200 feet at its southwestern part; thence along 
its western side it maintains this latter elevation to its northern line, 
where, in the northern part of the Pine Creek basin, it attains an 
elevation of over 2,600 feet. Along the remainder of the northern 
crest the height quickly falls to about 1,200 feet, but rises again to 
about 2,000 feet along the eastern crest of the divide. The highest 
points in the State are along the crest of this watershed. 

As far up as Queens Run the fall of this branch is comparatively 
small, while above that point, in the mountain region, it is much 
greater. Furthermore, the banks of both the stream and its tribu- 
taries above Queens Run are generally high, and there are few low 
grounds subject to overflow. Below Queens Run the river traverses 
a wide, fertile valley, without, however, overflowing its banks to any 
considerable extent. The bed of the river is generally gravel and 
sand, with a rocky ledge at places. In former years this portion of 
the drainage was largely used by lumbermen for floating logs. On 
most of the streams splash dams were built, sometimes flooding con- 
siderable areas, and serving to hold the logs which were sent down 
until a sufficient number were collected. The gates in the dam were 
then raised, letting the water out suddenly, so that the logs were car- 
ried down on the swell or wave to the next dam or to the main river, 
where the natural current would be sufficient to carry them along. 
As the forest areas are now largely cut off, but very little logging is 
done either on this or other portions of the river. 

Professor Rogers describes this branch of the river as follows : ^ 

The tipper part of the West Branch of the Susquehanna, and also its tributa- 
ries, the Sinnemahoning, Kettle Creek, Pine Creek, etc., draining the high plateau 
northwest of the Allegheny Mountains, flow through deep trenches in the hori- 
zontal strata, very analogous in their features to those which give passage to the 
Delaware and the Main or North Susquehanna, in the northeastern part of the 
State. Prom the mouth of the Sinnemahoning out into the Bald Eagle Valley,

24 HYDEOGUAPHY OF SUSQUEHANNA BASIN. [no. 100. 

the river hills are very high and steep, and admit extremely narrow strips of 
ground betvpeen their feet and the river, except near the oj^enings of the lateral 
streams. The trough through which the lower half of Pine Creek flows is equally 
profound. Entering the valley between the Allegheny Mountains and the Bald 
Eagle ridge, the river pursues a beautiful winding course the whole way from 
Lockhaven to the neighborhood of Muncy, alternately sweeping toward the 
middle of the cultivated valley and back again, close in to the base of the steep 
and wood-covered ridge. Near Muncy it turns with a broad majestic curve 
round the end of the Bald Eagle Mountains, and in a few miles deflects from a 
southwest to a west course, throtigh a highly fertile, richly cultivated open 
country, till it strikes the base of the Blue Hill, or range of red sandstone cliffs 
above Northumberland. Southwest of Muncy the river crosses a singular belt 
of deeply eroded country, full of conical hills. 

NAVIGATION. 

Information in regard to navigation along Susquehanna River and 
its tributaries is now only of historical interest. The official records of 
Pennsylvania and other papers published during the early part of the 
century show that from the first settlement Susquehanna River and 
its tributaries were regarded as a possible means of navigation. 

In this relation the following quotation from Dager's report is of 
interest : ^ 

General Sullivan, to punish the Six Nations, late in August, 1779, organized a 
force of 3,000 men and moved north from Wyoming, the artillery and stores 
being drawn up the North Branch in 150 boats. At Tioga he was joined by Gen- 
eral Clinton with 1,000 New York troops. The latter had marched from Albany 
to Otsego Lake, where, flnding the water too low to flo t his bateaux, he built a 
dam across the stream, by which the lake was raised several feet, and when the 
dam was cut away the discharge wavQfloated his boats down to Tioga. 

The Indians fled in dismay at the sigl^t of a flood in the midst of the summer 
drought, believing it a signal of the dis|pleasure of the Great Spirit. From this 
might be inferred that Otsego Lake could be made a reservoir to pay tribute to 
the river when there was an insufficient flow. 

On March 9, 1777, an act was passed declaring Susquehanna River 
a public highway as far down as Wrights Ferry, and later on, March 
31, 1785, the whole river through Pennsjdvania was declared a public 
highway. An appropriation of £6,290 was made as early as April 11, 
1791, for the improvement of the navigation of Susquehanna River. 
Other appropriations were made from time to time and active canals 
were maintained from Havre de Grace to the New York State line, 
on the West Branch from Northumberland to Lock Haven, and on 
the Juniata from Juniata Junction to Holidaysburg. 

Between 1800 and 1830 several plans were proposed for connecting 
Susquehanna River with the Great Lakes and Avith Mississippi River. 
Nothing, however, came of any of these projects, and with the com- 
ing of the railroads the canals were gradually abandoned, being in 
most cases bought by the railroad companies. The North Branch 
extension, from the New York State line to Pittston, was abandoned in 
1868 or 1869. The canal from Pittston down was used more or less

until the fall of 1874, but the high floods of the spring of 1875 caused 
so much damage that no boats were ran after that date above Wilkes- 
barre. The Lackawanna Canal served as a feeder for the Wilkes- 
barre Branch until the spring of 1882, when it was abandoned to the 
Nanticoke dam. The canals below Sunbury were abandoned about 
1890. 

MEASUEEMEIVTS OF FEOW. 

The records of the measurements of flow in the Susquehanna drain- 
age have been divided into two classes : First, those at regular sta- 
tions, where systematic observations have been carried on over a 
series of years; second, those at miscellaneous stations, which consist 
of short or broken series of observations. There have been nine reg- 
ular stations maintained, as given in the following list:

The locations of these stations are shown on fig. 1 (p. 11) by the 
letters in column 1 of the above table. 
Miscellaneous records have been collected at the following points: 

Chemung River at Chemung, N. Y. 

Tioughnioga River at Chenango Forks, N. Y. 

Cayuta Creek at Waverly, N. Y. 

Chenango River at Oxford, N. Y. 

Eaton and Madison creeks. 

Diversions from Chenango River drainage. 

The following pages give the data which have been collected at 
both regular and miscellaneous stations, also the results of the com- 
putations based upon these data. 

SUSQUEHANNA RIVER AT BINGHAMTON, N. Y. 

This gaging station was established by R. E. Horton July 31, 1901. 
The gage is located on the upstream side of the left span of the 
Washington street bridge. The bench mark is a chiseled draft on 
the corner of the left abutment on the upstream side. Its elevation

[no. 109. 



is 23.71 feet above gage datum. This bridge is located about 800 feet 
upstream from the junction of Chenango and Susquelianna rivers. 
A rift extends diagonally across the stream underneath the bridge. 
The gage is above a stretch of smooth water extending from the crest 
of the rift to the dam 2,800 feet upstream, and the gage readings are 
not affected by backwater from Chenango River at ordinarj^ stages. 
On account of unfavorable conditions of Washington Street Bridge 
discharge measurements are made at Exchange Street Bridge, which 
is 1,900 feet upstream. At this place the channel is about 300 feet 
wide at low water and, about 450 feet wide at high water, and is straight

for about 500 feet above and below the bridge. The bed is naturally 
gravel and small stones. Formerly a wooden footbridge was located 
at this point, and the channel was divided into three parts by two 
piers. Large stones were piled around the piers. At present a steel 
bridge occupies this site, and there is but one pier, above which are 
two rows of short piles and a quantity of small stones. The upper 
parts of the old piers have been removed, but the stone filling around 
them remains, leaving the river bed irregular and rough. 

The velocity is good at low water and swift at high water. The 
lowest observed mean velocity is 0. 72 foot per second.

Within tlie time for which this record has been kept, the gage 
height has ranged between 1.84 and 19.22 feet, and the estimated 
discharge between 400 and 60,300 cubic feet per second. 

The gage is read twice daily by E. F. Weeks.

34 HYDROGKAPHY OF SUSQUEHANNA BASIN. [no. 109, 

CHENANGO RIVER AT BINGHAMTON, N. Y. 

This station was established by R. E. Horton July 31, 1901. The 
gage is located on the upstream side of the first span from the right 
bank of Court Street Bridge, Binghamton. It is a boxed wire gage 
secured to the vertical supports of the hand railing. The bench mark 
is a circular chisel draft on the upstream corner of the bridge seat on 
the left abutment. Its elevation is 84.02 feet above gage datum. 
Court Street Bridge stands squarely across the stream, which has a 
nearly horizontal bed of gravel and small cobblestones, affording a 
smooth, uniform current for gaging. The channel is obstructed by 
three masonry piers supporting the four spans of the bridge, 79 feet 
clear width each, the bridge having a total length of 337 feet between 
abutments. The bridge is situated 2,500 feet above the confluence of 
Chenango and Susquehanna rivers. A small rift below the bridge 
cuts off backwater from the Susquehanna at ordinary stages of the 
rivers. For periods during freshets or at times when there is an 
abnormal rise on one stream, accompanied by a similar rise in the 
other stream, either the Chenango or Susquehanna River record at 
Binghamton may be affected by backwater, indicating a too great 
discharge. For freshets of considerable duration the flow of the two 
streams will be more nearly equalized. Gage readings on Chenango 
River, as well as those on Susquehanna River at Binghamton, are 
taken by E. F. Weeks. In estimating run-off of Chenango River the 
area directly tributary to storage reservoirs from which diversion is 
made to supply Erie Canal has \been deducted from the total area 
naturally tributary to Chenango River. 

In estimating the run-off of Chenango River the area directly tribu- 
tary to storage reservoirs, from which diversion is made to supply Erie 
Canal, has been deducted from the total area naturally tributary to 
Chenango River, as follows: 

Square miles. 

Nattiral tributary area « , 1, 580 

Diversion area, 6 reservoirs at head of Chenango River, whose overflow 

is turned into Erie Canal through Oriskany Creek 30 

Diversion area, De Ruyter reservoir, at head of Tioughnioga River; out- 
flow turned into Erie Canal through Limestone Creek 18 

48 

Net area used for Chenango basin 1, 532 

Above estimate of diversion area is approximate. No allowance 
for direct inflow to feeder channels from additional areas nor fo.' 
waste into original stream. Gross area, from which more or less run- 
off is diverted, is about 105 square miles. 

a From Bien's Atlas of New York State. Areas tributary to reservoirs are from New Yort- 
Barge Canal Report, 1900.

The daily discharge during January, February, and March is only approxi- 
mate, owing to the ice conditions. From March 4 to 22, 1904, the discharge was 
estimated from the measurement of March 8, which was approximately 50 per 
cent of normal conditions. This was due to an ice gorge.

SUSQUEHANNA RIVER AT WILKESBARRE, PA. 

The Wilkesbarre station was established by E. G. Paul ou March 
30, 1899. 

The standard chain gage is located on the upstream side of the 
Market Street Bi'idge. The length of the chain from the end of the 
weight to the marker is 40.83 feet. The gage is read once each da}^ 
b}^ W. S. Bennett, the bridge keeper. When this gage was estab- 
lished, there was found to be a gage ]3ainted on the bridge pier, 
being a portion of one established by the AVeather Bureau. The 
lower part of this gage, erected in Januarj^ 1898, originally consisted 
of heavy cast-brass plates graduated to feet and tenths. The gage 
plates were made in i-foot sections and bolted to the stone bridge 
pier. The two lower sections of the brass plates had been torn away 
by ice, so that there was no graduation below the 8-foot mark, but 
readings were made by the figures painted on the stone pier. The 
zero of this old gage is at the base of the dressed-stone portion of the 
pier and is reported to be 535 feet above sea level. During low 
stages of the river the water recedes from the pier, rendering it 
impracticable to read the gage. So far as could be ascertained, this 



44 HYDKOGRAPHY OF SUSQUEHANNA BASIN. [no. 109. 

has not been connected with the citj^ datnm. On account of tlie low 
water, which in 1897 liad gone below the city datum, it was decided 
to put the zero of the new gage 4 feet below the zero of the old 
Weather Bureau gage, so as to obviate minus readings. In order, 
therefore, to compare with former records, it is necessary to add 4 
feet to the old figures. The danger mark of this Weather Bureau 
gage is at 14 feet, or 18 feet of new gage, as at this elevation the 
west bank of the river is under water in places. River reports from 
this localit}^ were furnished as early as 1888. During low water 
measurements were made by wading at a better cross section, at 
Retreat, 10 miles below Wilkesbarre. The elevation of the Market 
Street toll bridge above the river bed requires 65 feet of cable to 
sound across the section. 

Observations of fluctuations of Susquehanna River are made by the 
Weather Bureau above Wilkesbarre, at Towanda, Pa., where the 
drainage area is estimated to be 8,000 square miles. The river gage, 
made of iron 1 foot wide and one-half inch thick, is on the east side 
of the road bridge over Susquehanna River, and is securelj^ bolted to 
the masonry of the pier. The graduation is from to 25 feet. The 
highest water was 29 feet in March, 1869, and the lowest, —0.1 foot, 
in October, 1895. The danger line is at 16 feet. The elevation of 
the zero is 633.7 feet. 

Discharge measurements are made from the downstream side of the 
bridge, which has a total span of 700 feet between abutments. The 
initial point for soundings is the end of the iron handrail on the left 
bank, downstream side. The ch^nel is straight for about one-fourth 
mile above and below the station.^ There is a bar across the river 
about one-half mile above the station, and another at about the same 
distance below, with deep water between these two points. This 
makes a sluggish current at low stages. The right bank is low and 
overHows at a gage height of about 20 feet. The left bank is above 
ordinary floods. The bed of the stream is composed of sand and 
gravel and is somewhat shifting. There is but one channel, broken 
by 3 bridge piers. There are a few willows growing under the right 
span. The bench mark is the extreme west end of the stone doorsill 
of the north entrance to the Coal Exchange Building. Its elevation 
is 32.99 feet above uase datum.

E. G. Paul.- It is located at the Mill Street Bridge, 600 feet south of 
the public square, Danville, Pa., near the Pennsj^lvauia Railroad sta- 
tion at South Danville. The box of the standard chain gage is bolted 
to the hand rail on the lower side of the bridge 200 feet from the right 
bank. The length from the end of the weight to the marker is 42.85 
feet. The gage is read once each day by E. F. Bell. Discharge meas- 
urements were made from the lower side of the Mill street covered 
wooden highway bridge. This bridge was carried away by the ice on 
March 9, 1904. From that time until the water dropped below gage 
height, 5 feet, its stage was observed on the Weather Bureau gage. 
After the water fell below 5 feet its stage was measured approxi- 
mately, until September 30, 1904, by means of temporary gages set 
by the gage reader. This bridge had a total span of about 1,300 feet. 
The initial point for soundings was at the end of the wooden hand rail 
on the left bank, downstream side. The channel is straight for about 
one-half mile above and below the station. The right bank is low and 
liable to overflow. The left bank is high and is not subject to over- 
flow~ The bed of the stream is rocky, with some gravel, and is per- 
manent. There is but one channel, broken by the six bridge piers, 
which do not obstruct the flow to any considerable extent. The cur- 
rent is moderately rapid, except at very low stages, when it becomes 
sluggish. The bench mark is the extreme south end of the stone 
doorsill at the east entrance to the city filter plant. Its elevation is 
31.7 feet above gage datum.

MEASUREMENTS OF FLOW. 



67 



WEST BRANCH OF SUSQUEHANNA RIVER AT M'lLLIAMSPORT, PA. 

This station was established March 1, 1895, by George D. Snyder, 
who was at that time city engineer. On August 16, 1901, a standard 
chain gage was installed on the uxjper side of the Market Street Bridge. 
It is i-ead once each day by Henry H. Guise, who is employed in the 
city engineer's office. The length of the chain from the end of the 
weight to the marker is 40.29 feet. Discharge measurements are made 
from the lower side of the Market street iron highway bridge. The 
initial point for soundings is the face of the abutment on the left bank. 
The channel is straight for several hundred feet above and below the 
station, is broken by four bridge piers, and is about 1,000 feet wide 
at the station. There is a dam about one-half mile above the station. 
Both banks are high and rocky. The bed of the stream is composed 
of gravel and silt, and will probably change to some extent in the 
shore spans. The current velocity is sufficient for accurate measure- 
ment, except at extreme low stages. The bench mark is a cut in the 
face of the left abutment 10,07 feet above gage datum.

Pa., 1901-1904.

84 HYDROGRAPHY OF SUSQUEHANNA BASIN. [no. 109, 

WEST BRANCH OF SUSQUEHANNA RIVER AT ALLENWOOD, PA. 

Observations of height of water on the West Branch have been 
made by the Weather Bureau at Lock Haven, Pa., 47 miles above 
Allenwood. The drainage area is given as 3,740 square miles, and 
the width of river 1,125 feet. The gage is in two sections. The lower 
section is painted on the side wall of the canal lock and the upper is 
on the highway bridge over the river. The elevation of the zero is 
555.7 feet. The highest water was 18 feet, on June 1, 1889, and the 
danger line is at 10 feet. 

A gaging station was established on the West Branch by E. G. Paul 
on March 25, 1899, at Allenwood, Pa., 20 miles above the junction 
with the main stream. Measurements are made from the public 
highway bridge, one-fourth of a mile east of the railroad station at 
Allenwood. The wire gage is 42.15 feet from zero to the end of the 
weight, and is referred to a pine-board scale fastened to ironwork of 
the bridge and divided into feet and tenths. The initial point of 
soundings is at the end of the iron guard rail on the right bank. The 
channel is straight for one-half a mile above and below the station. 
The current is sluggish, but unobstructed. The banks are low and 
subject to overflow at time of high water. The bed of the stream is 
rocky and permanent. The observer is Frank L. Allen, a farmer, living 
200 feet from the gage. A bench mark was established on September 
24, 1900. It consists of a copper bolt set in the capstone of the wing 
wall on the lower side of the west end of the bridge, and is 33.19 feet 
above datum of the gage. 

This station was discontinued in April, 1902, the station at Wil- 
liamsport taking its place.

ANDEKSON.] MEASUBEMENTS OF FLOW. 93 

JUNIATA RIVER AT NEWPORT, PA. 

Juniata River rises in Center County, Pa., and flows in a general 
southeasterly direction into Susquehanna River 15 miles above Har- 
risburg. Its drainage area is mountainous and for the most part 
covered with forest growth. 

This station was established at Newport, about 15 miles above the 
mouth of Juniata River, March 21, 1899, by E. G. Paul. The standard 
boxed chain gage was located on the covered wagon bridge which was 
800 feet east of the public square at Newport, Pa. It was attached to 
the bridge timbers inside of the bridge near the right bank. The 
length of the chain from the end of the weight to the marker was 39.54 
feet. The gage is read once each day by A. R. Bortel. Bench mark 
No. 1 is on the extreme east end of the stone doorsill, south front of 
Butz's store building, near end of bridge; its elevation is 28.83 feet 
above gage datum. Bench mark No. 2 is on shelf in southeast corner 
of underpinning of store of J. M. Ewing; its elevation is 27.37 feet 
above gage datum. This bench mark was set by the Pennsylvania 
Railroad, and according to their records its elevation is 390.69 feet 
above sea level. Discharge measurements were made from the lower 
side of the four-span wagon bridge to which the gage was attached. 
The initial point for soundings was the end of the woodwork of the 
bridge on the right bank downstream side. In the fall of 1904 this 
bridge was replaced by a steel structure. -During its construction the 
stage of the river was obtained by means of a temporary gage staff 
attached to the exposed end of a sewer near the bridge. This gage 
was set at the same elevation as the old one. As soon as the bridge 
is completed a standard chain gage will be put in place. The chan- 
nel is straight for one-half mile above and below the station. Both 
banks are high and are not subject to overflow. There is a single 
channel, broken by three bridge piers. The piers do not interfere with 
the flow of the stream and there is little eddying and boiling near 
them. The bed is of hard material and is probably permanent. 
There is a good measurable velocity at all stages.

SUSQUEHANNA RIVER AT HARRISBURG, PA. 

In 1890 regular daily observations of fluctuations of the water 
surface of the Susquehanna River at Harrisburg were started by 
E. Mather, president of the Harrisburg water board. These observa-

tions have been continuecl since that time and have been furnished 
through the courtesy of Mr. Mather. 

The gage, the zero of which is the low-water mark of 1803, is located 
at the pump house of the waterworks in the pump well, which is 
connected with the river by two large mains. The original readings 
are taken in feet and inches, and for convenience in computations 
have been reduced to feet and tenths. 

The first discharge measurement was made at this station in March, 
1897, by Mr. E. G. Paul, who has carried on systematic measure- 
ments there since that date. The measuring section is at the lower 
side of the Walnut street toll bridge. The initial point for soundings 
is the upright at the end of the hand rail on the downstream side on 
the left bank. 

At this point the river is divided into two channels by Fosters 
Island, which at the measuring section is about 1,200 feet wide. Its 
banks are low and sloping and during extreme floods the island is 
submerged. 

At ordinary stages the left channel is 1,350 feet wide and is broken 
by six bridge piers. The right channel is 1,300 feet wide and is 
broken by seven piers. The main banks of the river are high. The 
bed is composed of a hard matei-ial and is permanent, except in the 
spans adjacent to the island. The velocity never becomes too slug- 
gish to measure. 

During the spring and summer of 1903 a new bridge was built 
across Susquehanna River at Market street, which is about 1,200 feet 
below the gaging section. The piers of this new bridge obstruct 
the channel of the river by between 10 and 15 per cent of the total 
cross section. The result of this obstruction, as shown by the dis- 
charge measurements taken since the erection of the piers, has been 
to back up the water, thus increasing the gage height at the Walnut 
street station. On account of this backwater the measurements 
taken during 1903 show that, in order to use the standard rating table 
after June 1, 1903, and until January 1, 1904, a deduction of 14 per 
cent is necessarj- in the daily discharges. The following table gives 
the data from which this deduction was made :

HYDEOGRAPHY OF SUSQUEHANNA BASIN. 



[NO. 109. 



About January 1, 1904, the old piers which were standing at the 
site of the new bridge at Market street were removed^ so that the 
river channel was left in such a condition that the stage of the river 
at Walnut street bridge returned to the same condition that existed 
before the 1903 bridge was built. 

In the summer of 1904 certain changes and improvements were 
made at the pumping station, and a partial dam was made in the river 
just below the pumping station. The effect of this dam was to raise 
the apparent stage of the water at the gage. A correction was applied 
to measurements of discharge made prior to July 18, 1904, so as to 
eliminate the effect of the dam and alterations at the pump house 
upon the gage readings. 

On July 18, 1904, a standard chain gage was attached to the guard 
rail on the upstream side of the Walnut Street Bridge in the left- 
hand span. The datum of this gage is the low-water mark of 1803, 
ajid it is believed that it records trulj^ the stage of the river to that 
datum, and that the changes in bridges below and at the pumping 
station above do not affect the records obtained from it. 

The length of chain is 39.38 feet; the bench mark is on the left abut- 
ment at the top upstream outer corner of the bridge seat; its elevation 
is 32.99 feet above low water of 1803. 

Observations at the gage in the pumping station are made by 
the engineer, C. M. Nagle, each morning before starting the pump. 
Observations at the standard chain gage are made by Thomas Num- 
bers, toll collector, once daily. 

The following pages give the data which have been collected at 
Harrisburg gaging station since its establishment; also the results of 
the computation of these data.

oProm January 1 to July 17, inclusive, gage readings were taken at the pump house. Prom 
July 18 to the end of the year the readings were taken at the Walnrit Street Bridge. Beginning 
with April 1 the readings at the pump house were too high by 0.6 toot, owing to the fact that a 
cofferdam was built just below the intake. This correction has been applied; therefore the gage 
readings for the complete year are referred to the low-water datum of 1803. 

b River frozen over at 5 a. m. 

f Several ice gorges existed both above and below Harrisburg from January 24 to March 13. 
These caused the backing up of the water, thus increasing the gage height.

"Owing to an lee gorge below Harrisburg the monthly mean for January, February, and 
March has been estimated by taking 89 per cent of means for McCalls Ferry. Practically open 
conditions existed at the latter station (gee p. 18.S). 



130 HYDKOGEAPHY OF SUSQUEHANNA BASIN. [no. 109. 

SUSQUEHANNA RIVER AT McCALLS FERRY, PA. 

The McCalls Ferry gaging station is located, as shown in PI. VIII, 
at a narrow and rocky part of Susquehanna River, about 20 miles 
above its mouth and 1 mile above the village of that name. It was 
established on May 17, 1902, by Boyd Ehle while investigating a power 
development there. For a considerable distance along this j)ortion of 
the river the bank on the York County shore is the retaining wall of 
an abandoned canal which can be overtopped only in the greatest 
floods. The Lancaster shore, on the opposite side, is made up of 
almost vertical rock, and the railroad which skirts it has never yet 
been flooded at this point. 

The gaging section first selected for the station is located at Dun- 
cans Run (A- A, PL VIII), where two islands, Hartman and Streepers, 
divide the river into three channels, ranging in width from 100 to 500 
feet. At ordinary low water, however, two of these run dry, thus 
confining the discharge to the main or westernmost channel. The 
river bed at the section is composed of schistose rock, with some pro- 
jecting bowlders and large irregularities. The flow, however, is com- 
paratively free from the boils so common in a river of this character. 

The discharge measurements are made from a boat held in place 
by a rope stretched between the towpath and Streepers Island, the 
gaging points, 10 feet apart, being indicated bj'^ a tagged wire, which 
is also used for keeping the boat parallel to the current. 

In order to provide for measuring the large floods which occur in 
the winter and spring months a cable station was established bj^ Mr. 
Ehle in the fall of 1902, about 1,000 feet downstream from the Dun- 
cans Run section (B-B, PI. VIII). The banks of the river and the 
condition of the river bed are very similar to those at the upper sec- 
tion, though the latter is somewhat more irregular, as shown by PI. 
I, B. During the low- water period of the fall of 1902 a careful sur- 
vey was made of the section at the cable station, and a contour map 
with 1-foot intervals was prepared from which the effective areas 
could be accurately determined, thus eliminating the error in dis- 
charge due to possible inaccuracies in soundings made at the time of 
the measurements. The width of the stream at this point is about 
1,300 feet, and the maximum depth during a gaging was 46 feet. 

The car cable, a f-inch 37-wire strand, with a span of 1,450 feet, is 
anchored to 3-inch ej^ebolts set in cement in the solid rock on either 
side of the river. A 2-inch turn-buckle is provided at the York 
County end to regulate its height above the water. A high cliff on 
one shore and a large red oak on the other give the cable a 10-foot 
clearance over the highest floods on record. The car which runs on 
the cable, as shown in PI. IX, B, accommodates two people, and is 
propelled by a crank, turning one of the sheaves. 



HOYT AND 

ANDERSON

Eighty feet upstream from the main cable is suspended a f-inch 
secondary cable, along which runs a trolley carrying a guy rope to 
hold the meter against the current (PL IX, A). Measuring points 
for this section are 50 feet apart and are indicated by red and white 
bands ijainted on the main cable, the intermediate distances being 
readily estimated by counting the revolutions of the sheave. 

The measurements at both of the above stations are referred to two 
permanent gages, designated Nos. 2 and 5. These are painted on the 
rock and give elevations directly above sea level. Gage No. 2 is 
located about three-fourths of a mile below the village of McCalls 
Ferry in the tailrace of the proposed power house and has been read 
daily since June, 1902. The records in the following tables have 
been referred to this gage. Gage No. 5 is placed about 2 miles 
below McCalls Ferry, at the foot of Cullys Falls, and was thus located 
in order to be entirely out of the influence of the proposed dam. One 
of the purposes of the extensive investigations carried on at McCalls 
Ferry was to obtain data for determining the coefficient of discharge 
over ogee-faced weirs under high heads, and it is for use in these 
investigations that gage No. 5 was established. 

The methods used in carrying on the work at the McCalls Ferry 
station were practically the same as those employed by the United 
States Geological Survey. Every effort was made to eliminate any 
source of error, and vertical velocity determinations were taken when- 
ever possible. At Duncans Run, in order to ge^ satisfactory ver- 
tical velocity curves, an 80-pound weight, with pulley and rope 
attached, was dropped to the bottom, so that the meter could be 
pulled down without being washed too far from the section. When 
the surface velocity or 0.6 method was used the results were reduced 
by coefficients determined from these vertical velocity curves. At 
the cable station the secondary cable with the aid of the guy rope 
made it possible to get vertical velocity measurements at exception- 
ally great velocities and depths. A No. 12 telegraph wire was found 
to be more satisfactory at such times for holding the meter than the 
insulated cable ordinarily used, as it offered less resistance to the 
current, would allow the meter to sink deeper, and being less bowed 
by the water would show more accurately its depth below the sur- 
face. In this way curves were obtained to depths of 20 feet and in 
currents of 10 feet per second. 

During the highest stages, when the velocity sometimes reaches 17 
feet per second, readings could only be taken at the surface. These 
results were, however, reduced by coefficients determined from the 
vertical velocity curves for each measuring point.

140 HYDEOGEAPHY OF SUSQUEHANNA BASIN. fxo. 109. 

CHEMUNG EIVER AT CHEMUNG, N. Y.« 

A gaging statiou was established at tlie suspension bridge across 
Chemung River near Chemung station, September 7, 1903. Gage 
heights are taken each morning and night, by Daniel L. Orcutt, b^^ a 
chain gage attached to the bridge. Current-meter measurements 
which have been made, and the mean daily stage of the stream, are 
shown in the accompanying tables. The gaging station is located 1 
mile upstream from the New York-Pennsylvania line, and is shown 
on the Waverly sheet of the United States Geological Survey's topo- 
graphic map of the country. 

Chemung River is formed at Painted Post, N. Y., by the union of 
Tioga and Cohocton rivers. The Cohocton branch lies entirely in 
the State of New York. Tioga River receives, just above its mouth, 
Canisteo River, a large tributary, which also has its drainage basin 
in New York to the south of the Cohocton. The drainage of Tioga 
River above the Canisteo is mainly in Pennsylvania. The concen- 
tration, just above Corning, of the storm waters of these three main 
branches favors the formation of excessive floods. 

Chemung River flows southeasterly through Corning, Elmira, and 
Chemung, crosses the State line, flows for a short distance in Penn- 
sylvania, then returns to New Yoi'k and again crosses to Pennsylva- 
nia near Waverly, finall}'- emptying into Susquehanna River near 
Athens, Bradford Countj^, Pa. The total length of the stream is 
about 40 miles, about 30 miles of which is in New York State. Che- 
mung River is a sluggish stream with low^ banks and a broad valley 
or flood plain, which is often overflowed. It was formerly paralleled 
by a canal taking its supply from dams across the stream. This has 
been abandoned and at present the largest water-power development 
on the main river is at Elmira. 

The topographic features of theSirainage basin are, as a rule, bold 
and broad. The hills rise within a short distance of the stream 
several hundred feet on either side, and the upland plateau is to a 
large extent wooded, with impervious soil, no lake storage, and few 
marsh areas. Tributaries are ramifj'ing and uniformly distributed, 
though not numerous, and dry gulleys or flood channels are common. 
Dikes have been erected in the cities of Elmira and Corning for pro- 
tection against floods. One of the highest recorded freshets in the 
stream occurred June 1, 1889. It was preceded by phenomenal rain- 
fall, on the night of May 31 and June 1, aggregating several inches 
in the course of a few hours. The discharge has been estimated at 
67 second-feet per square mile from 2,055 square miles, or 138,000 
cubic feet per second.*

The above table is applicable only for open-channel conditions. It is based 
upon 8 discharge measurements made during 1903 and 1904. It is fairly well 
defined between gage heights 1.90 and 3.30 feet. The table has been extended 
above gage height 6.70 feet. Above gage height 8.0 feet the rating ciirve is a 
tangent, the difference being 300 per tenth. The rating table has been applied to 
the nearest hundredth of a foot to gage height 6.00, to the nearest half -tenth of a 
foot to gage height 9.00, to the nearest tenth of a foot above gage height 9.00 
feet.

TIOUGHNIOGA RIVER AT CHENANGO FORKS, N. Y. 

During the fall of 1903 the gaging station was established at this 
point in order to determine the low- water flow. Owing to the heavy 
rains which occurred that fall, as showii by the following table, the 
stage of the river did not fall as low as was expected.

gagings, except at extreme high waters. Gage readings were taken 
during October and part of November from a staff gage fastened to 
the right-hand face of the center pier of the bridge. The drainage 
area of Tioughnioga River above the mouth at Chenango Forks, 
including the areas naturally tributary to the Tioughnioga, but now 
diverted to supply Erie Canal through the Erieville and Deruyter 
reservoirs is 735 square miles.

CAYUTA CREEK AT WAVERLY, N. Y. 

A record of the daily stage of Cayuta Creek at the Ithaca Street 
Bridge, a short distance below the milldam in Waverly, was kept by 
T. P. Yates, covering the period'lklarch 1, 1898, to March 31, 1902. 
Tlie accompanying tables show the observed distance from the refer- 
ence point on bridge to water surface, the mean of the several read- 
ings being used where more than one daily observation was taken, « 
Discharge measurements by means of floats were also made by Mr. 
Yates. 

Cayuta Creek drains a long, narrow valley extending from eastern 
Schuyler County in a direction somewhat east of southerly a distance 
of 30 miles, the stream crossing the New York State line at Waverly 
and emptying into Susquehanna River at Sayre, Pa. In cross section 
the valley consists of a plain about one-half mile wide, through which 
the stream flows, bordered on both sides by abrupt slopes rising 500 
feet within a distance of 1 or 2 miles from the foot on each side, 

"Befei-ence point is top iron hand rail at left-hand side second iron post from left-hand end of 
bridge on upstream side.

beyond which lies a plateau, cut by the numerous short lateral trib- 
utaries and their branches. 

Cayuta Lake drains an area of 1G.5 square miles at the head of the 
stream. The area of the lake is 0.78 square mile, and this constitutes 
the onl}^ storage in the drainage basin. The average width of the 
valley is about 6 miles. The conditions favor rapid concentration of 
the run-off in the main stream, there being no large branches. Maxi- 
mum floods result, however, only from rapid inflow of sufficient dura- 
tion to enable the waters from the whole length of the valley to reach 
the lower stretches of the stream at the same time. Cayuta Lake is 
at elevation 1,272 feet. The stream descends to elevation 800 feet at 
Waverly in a distance of 18 miles from Cayuta Lake, following the 
general trend of the valley, a limited amount of water power being- 
developed at small dams.

CHENANGO EIVEE AT OXFOED, N. Y. 

A temporary board gage was attached to the upstream side of the 
left-hand abutment of the highwaj^ bridge across Chenango River at 
South Oxford, N. Y., September 29, 1903, and observations of the 
stream stage were taken twice daily from that date until November 
7, 1903. The desired data relative to low-water flow could not be 
obtained on account of heavy rains. The precipitation during the 
period of observation, as recorded at Oxford, is given below :

EATON AND MADISON BROOKS, MADISON COUNTY, N. Y. 

Records of the flow of Eaton and Madison brooks, two small streams 
near the headwaters of Chenango River, are among the earliest, if not 
the fi.rst, systematic stream gagings in the United States. The flow 
of these streams was determined by John B. Jervis in 1835 in an 
investigation of water supply for the summit level of Chenango 
Canal, extending from Utica to Binghamton, and now abandoned. 

Tfe3 headwaters of Chenango River, including Eaton and Madison 
brooks and the storage reservoirs which have been constructed to 
supply the summit level of Erie Canal through Oriskany Creek, are 
shown on the Morrisville, Cazenovia, Norwich, and Pitcher sheets of 
the United States Geological Survey topographic map. 

Eaton Brook drainage basin is from 1| to 3 miles in width and 7 
miles in length. It contains near its head Eaton reservoir, at an eleva- 
tion of about 1,430 feet. The slopes are steep; the soil is close tex- 
tured, with shale near the surface. Tributaries are few, and the fall 
is rapid. 

The soil and topography of Madison Brook are similar, the area con- 
sisting of rounded hill slopes with a somewhat more porous soil, 
greater breadth, and more tributaries than in the Eaton Brook area. 

It is stated that the Eaton Brook and Madison Brook gagings show 
only the volume of water passed downstream from the reservoirs.

DIVERSIONS FROM CHENANGO RIVER DRAINAGE BASIN. 

An examination was made of the diversion from Chenango River 
drainage basin to supply Erie Canal during September, 1903. 

Proceeding upstream from along the feeder which enters Oriskany 
Creek at Solsville, the draft from the storage reservoirs was observed 
as follows : 

Leland Ponds, well drawn down, September 11, 1903, outflow about 
9 second-feet, 

Chenango Feeder above inflow from Leland Ponds, September 11, 
1903, about 30 se ond-feet. 

Approximate total diversion, 39 second-feet. 

The outflow from the several reservoirs proceeding upstream was 
approximately as follows: 

Madison reservoir, September 11, 1903, 10 second-feet. 

Flow in Chenango feeder at first bridge above Hamilton, also above 
Madison reservoir outlet, about 23 second-feet. 

The outflow from the remaining reservoirs in the Chenango River 
area, Kingsley, Bradley Brook, and Eaton reservoirs, respectively, 
was slight. Their combined outflow passes a diverting dam above 
Randalsville, the waste from which, together with waste and seepage 
from the feeder, enters the natural channel of Chenango River, The 
flow in this river channel at the bridge above Earlville September 12, 
1903, was approximately 44 second- feet. 

PRECIPITATIOlsr. 

During the last few years the United States Weather Bureau has 
maintained about 47 precipitation stations in the Susquehanna River 
drainage area (see list on p, 160). The locations of these stations and 
of the gaging stations are indicated in flg. 1 (p. 11). 

In order to compare the relation of rainfall to run-off in the Sus- 
quehanna basin, the run-off at Harrisburg has been taken as repre- 
sentative of the whole basin, and that at Wilkesbarre and Williams- 
port as representative of the main stream above Sunbury and the 
West Branch, respectively. 

The rainfall stations are so distributed as to represent fairly well 
the conditions over each of these areas. Therefore, it is assumed that 
for any one month the mean rainfall over the whole of any of these 
areas is the mean of the monthly rainfall at the various stations in 
that area. Based upon this assumption, the monthly and yearly 
rainfall for each of the years when the run-off records are available 
has been determined, as shown in tables on pages 161-171. 

An examination of the tables on pages 156 and 157, which give a 
comparison of the rainfall and run-off above Harrisburg, shows that 
the mean annual rainfall over the drainage area varies from 31.4 to 

a Snow of November and December, 1904, on ground. 



HOTT AN 
ANDERSON 



°] PRECIPITATION. 155 



44.3 inches, with a mean for the fourteen years of 39.4. This jaelds 
a run-off of from 16.6 to 29.1 inches, with a mean of 21.6. The amount 
of rainfall which runs off varies from 49 to 71 per cent of the total, 
with a mean of 54 per cent. The run-off is a minimum in August, 
September, and October, during which months it ranges from 5 to 30 
per cent of the rainfall, and averages about 15 per cent. 

As complete snowfall data are not available, it has been impossible 
to allow for the snow storage, which accounts for the high percentages 
in the late winter and early spring. To fully account for this storage 
a cube of snow should be melted at the end of each month in order 
to determine the amount of water stored during that time. The 
quantity available for run-off during the following month would be 
the amount so determined plus the precipitation during the follow- 
ing month minus the amount left in snow storage at the end of that 
month. Unfortunatelj^ sufficient data of this kind are not available, 
and therefore no attempt has been made to account for this disturb- 
ing feature. 

The tables on pages 158 and 159 show that the conditions on the 
main stream above Wilkesbarre and the West Branch taken separately 
are practically the same as when taken together in connection with 
the entire river as referred to above.

HYDROGRAPHY OB^ SUSQUEHANNA BASIN, 



[no. 109. 



FLOODS. 



During the last century there have been several great floods on 
Susquehanna River, the most notable of which are those of March, 
1865; June, 1889 (the Johnstown flood); May, 1894, and March, 1904. 

The flood of 1865 was the result of the rapid melting- and jDassing 
away of a large quantity of ice and snow wliich had accumulated 
during an exceptionally severe winter. The amplitude of this flood 
was probably increased by ice gorges. No information in regard to 
the height of this flood has been obtained except that at the junction 
with the West Branch the river was 2 feet higher than during the 
June flood of 1889; .and the old residents along other portions of the 
main river state that this flood was approximately the same as the 
June flood of 1889. 

The flood of June, 1889, caused by the heavy rainfall of May 30 to 
June 1, probably exceeded any flood which has ever occurred on this 
stream. Being' in the summer months, it was not augmented by ice 
gorges, and therefore illustrates the normal effect of high-water con- 
ditions. The table below, taken from the report of the Chief of Engi- 
neers, U. S. Army, shows the extent and duration of rainfall within 
the limits of the West Branch; it Avas upon the high table-lands of 
this portion of the basin that the heaviest precipitation took place. 

Rainfall over drainage area of West Branch, May 30 to June 1, 1889.

in the Susquehanna drainage area reaches the outlet of the river. 
It is probable, however, that under extraordinary conditions, such as 
mentioned above, there was a run-off of at least 75 per cent of the 
rainfall. 

Vaa'ious methods of estimating the maximum discharge of the 1889 
flood have been used, perhaps the most reliable indicating that about 
593,000 second-feet flowed past Harrisburg, and 671,000 second-feet 
past McCalls Ferr3^ The basis of these estimates is shown in Pis. XI 
and XII, the other methods and results being given on pages 177 to 180. 

Pis. XI and XII were prepared as follows : The mean velocities for 
the varions discharge measurements taken at the respective stations 
were plotted with gage heights as ordinates and mean velocity in feet 
per second as abscissae. Through these points a mean velocity curve 
was drawn and extended to reach the highest gage height of the 
flood. This curve shows the mean velocity for any stage of the 
river. The crest of the 1889 flood at Harrisburg was 27.1 feet 
above the low water of 1803 and at McCalls Ferry cable station 
about 162 feet above mean sea level. The curves show that the 
mean velocities for these heights are 7.24 feet per second and 11.90 
feet per second, respectively. At each of these stations an accurate 
cross section was determined, and the product of the area below the . 
flood line and the mean velocity for that gage height, as taken 
from the extended mean velocity curve, gives the flow of the river. 
In this method of estimating flood discharges the uncertainty due to 
the area of the cross section, as when the discharge curve is produced, 
is eliminated. A study of other mean velocity curves made in this 
manner shows that the liability to error in the mean velocity is 
comparativelj'" small, and it is probable that this method gives a 
better estimate than either Kutter's formula or the discharge curve. 

The result is a maximum flow at McCall Ferry about 13 per cent 
greater than at Harrisburg, which accords with the assumption that 
the discharge between two points on the same river where the drain- 
age area is similar should increase in proportion to the drainage area. 
At McCalls Ferry the drainage area is 11.4 per cent greater than at 
Harrisburg. 

The loss of life caused by the flood within the drainage area of the 
"West Branch was 78, and the flood relief commission disbursed 
nearly $300,000 to the sufferers within this district, but no attempt 
was made to secure even an approximate estimate of the damage. 
The flood of May, 1894, near McCalls Ferry was 2 or 3 feet lower than 
the 1889 flood. 

The primary cause of the flood of March, 1904, was the breaking up 
of the ice in January without enough water behind it to force it down

its branches, which were greatly solidified by the exceptionallj^ cold 
weather in the following month. When the final break came these 
gorges w^ere still further augmented and acted as dams, impounding 
the large quantity of water which was so destructive to property along 
the shores. 

On March 6 and 7 there were heavy rains all over the drainage 
area, and on the morning of March 8 the floods so caused began to 
break through the various barriers. It finallj^ forced the big gorges at 
Highspire and Bainbridge, wiping out islands and doing much damage 
in its course. 

After the flood had subsided at York Haven, the gorge moved to 
Turkey Hill, where it stood for several hours and backed the water 
to within a few feet of the Columbia Bridge. Between 1 and 2 p. m. 
this gorge in turn gave way and moved to Shanks Ferry, where it 
gorged for the last time. Although it held here for only a few 
moments, it raised the water and ice 6 feet above the railroad track 
at Safe Harbor, completely .destroying the stone-arch bridge there 
and leaving ice throughout the village to the height of the second-story 
windows. 

The elevation of the crest of the flood, as shown for a portion of 
the river by the table on page 175, varied in height at various places 
along its course, as compared with the June flood of 1889. At York 
Furnace the height was about 3 feet greater; about a mile above 
McCalls Ferry it was practically the same; at McCalls Ferry station it 
was 3 feet lower, and at the head of Cullys Falls it was again about 
the same height. 

There came down with the flood wave a large amount of ice, which 
varied from 3 to 10 feet in thickness, as shown by the blocks left on 
the shores. Owing to the cross currents in the river, the greater por- 
tion of the ice went down on the York County side, and it was on this 
side that most of it was left pited up on the shores. The channel on 
the Lancaster County shore soon cleared itself, and but little ice accu- 
mulated upon that bank. 

The gorge at Turkey Hill broke about 2 o'clock in the afternoon, 
and at 3.30 p. m. the water reached a maximum height at McCalls 
Ferry. At the cable station it was 161.3 feet above sea level on the 
Lancaster County side and 159.8 feet on the York County side. 
Within half an hour from the time the maximum height was reached 
the water had fallen from 2 to 3 feet, and on the morning of March 9 
it had fallen 15 feet. 

Between Shanks Ferry and Port Deposit no more ice jams were 
formed, and the ice passed through the channel of the river very 
rapidly and caused but little damage. The history of nearly all 
floods has been that between "The Neck" and Port Deposit but little 
gorging takes place and that the river rapidly clears itself from any

ioe and seldom rises to such n lieight as to cause i)articular damage 
along the shores. At Port Deposit there is frequent trouble, for the 
shallow sand bars and tidal backwater often cause gorges which flood 
the tracks and lower part of the town.

Above Shanks Ferry much damage was done, and the loss of prop- 
erty was great at many points. The facts are interesting to those 
who contemplate power development in the lower portion of Sus- 
quehanna River, as the possible damage from ice has been one of the 
great objections to such development. 

The full eifect of the flood on the main stream was not felt below 
Sunbury, being restrained by the big gorges at Kipps Run, Catawissa, 
and Nanticoke, which held several days longer. It was at its worst 
in Wyoming Valley on the 9th, doing much damage to Plymouth, 
Wilkesbarre, and Pittston, and then quietly passed away without 
noticeable effect on the lower river.

FLOOD DISCHARGES AIS^D VALUES OF "N" BY KUTTER'S 

FORMULA. 

Owing to the lack of hi^- water gagings on Susquehanna River, it 
became necessary to estimate the flood discharges by means of the 
slope formula, v=cy/Rs, using Kutter's formula to fix the value of c 
The 1889 flood is the highest on record, and as there remain raanj' of 
its high-water marks made by eyewitnesses along the railroad and 
canal above McCalls Ferry, Pa., the mean slope along this part of the ' 
river could be closely approximated. These marks consist of notches ! 
on posts, rocks, hotels, bridge piers, and locks, and their elevations 
were accurately determined, as shown on the proflle. 

Ten sections, located as shown on PI. XVIII, were then chosen f i-oin 
the contour map. These were selected so as to show as far as possible 
the average for the portions of the river represented, so that the mean 
slope between the nearest reliable high- water marks could be used in 
connection with them. The sections were carefully surveyed and 
sounded to determine their area and wetted perimeter. 

In order to get a value for n in Kutter's formula the slopes were 
measured on the west channel of the Duncans Run section during

n At Duncans Run. 



''At section No. 10. 



The three measurements at Duncans Run give a coefficient of 
about 0.046. The conditions there are exceptionally favorable for 
this part of the river, so that as the flood sections in many cases 
included brushy and wooded islands, the value of n as used in the 
computations was increased to 0.05. 

The data and results showing the discharge at the respective sec- 
tions during the 1889 flood are shown in table on page 180. 

The mean of the discharges of these 10 sections gives a maximum 
for the 1889 flood of about 730,000 second-feet, or 9 per cent greater 
than the mean velocity curve estimate of 671,100 second-feet. (See 
pages 177 and 180.) 

In this connection it is of interest to note that if a coefficient equal- 
ing 0.055, as determined bj^ the single measurement at section 10, 
based upon the flood gaging of March 8, 1904, had been used, the 
mean discharge for the 1889 flood would have been about 685,000 
second-feet, or only 2 per cent greater than the results obtained by 
using the mean velocity curve. 

The general equation of the discharge curve shown on PI. X is 
approximately that of the parabola (^ — 111)^=:. 00202 x, which for a 
gage height of 149.5 gives the 1889 flood discharge as 733,800 second- 
feet. 

From these estimates it may be assumed that the maximum dis- 
charge of the 1889 flood was between 670,000 and 735,000 second-feet.

LOW-WATER CONDITIONS. 

At the time of the establishment of the gage at Harrisburg, in 1891, 
the lowest-known water on Susquehanna River was in 1803, and 
the zero of the gage was placed at the elevation of this low water. 

The months of August and September, 1900, were periods of extreme 
drought, and beginning with the 1st of Sei)tember the observations 
at Harrisburg showed a gradual falling of the river until September

1803. During tliis period of low water Mr. E. G. Paul, hydrographer, 
United States Geological Survey, spent considerable time in measuring 
the flow at the various stations in the Susquehanna drainage basin. 
On September 21 a measurement was made at Harrisburg at a gage 
height of ^0.08 of a foot and a discharge of 2,655 second-feet. Mr. 
Paul returned to Harrisburg on September 28, at which date the river 
reached its extreme low point of —0.04 of a foot, and made a meas- 
urement giving a discharge of 2,357 second-feet. 

The measurements made by Mr. Paul during the week of Septem- 
ber 28, 1900, at Allenwood, Danville, and Newport, Pa., as shown by 
the table below, gave a very close check upon the Harrisburg work, 
and show that the measurements as made at the various points along 
the river are consistent among themselves and that no errors greater 
than would be expected in work of this kind exist.

From the best available authorities the elevation of lowest water, 
in September, 1900, at McCalls Ferry, gage No. 2, was about 112.6 
feet. The measured minimum discharge at Harrisburg for that 
month was 2,357 second-feet, and by increasing this figure 11.4 per 
cent, to allow for the increase in drainage area, we find the corre- 
sponding maximum discharge at McCalls Ferry to be about 2,620 
second-feet. In order to check this result, the mean velocities of 
the various discharge measurements made at Duncans Run have 
been plotted as abscissae and their respective gage heights as ordi- 
nates, as shown in PL XIX. These points, it will be seen, seem 
to follow a general law, and a curve has been drawn through them

which has been extended Ihi'ough tlie gage lieight of the lowest 
water, which at Duncans Run was about ll-l:.2 feet. Tlie velocity 
from the curve for that gage height is 1.0 foot per second, and the area 
of the section is 2,940 square feet, the product of these two giving 
a discharge of 2,940 second-feet as a rough check on the above. 
The lowest water actually measured at McCalls Ferry was on Sep- 
tember 25, 1902, at a gage height on gage No. 2 of 114.34 feet, giving a 
discharge of 6,370 second-feet. The mean discharge from the rating- 
table atHarrisburg on that date was 5,760 second-feet, corresponding 
to a difference in drainage area of 10.6 per cent. The table on page 
178 gives the minimum estimated discharge at Harrisburg for the 
years 1891 to 1904, inclusive. 

ACCURACY OF STREAM MF.ASUREMEl^TS. 

Considerable comment has been made upon the hj^drographic 
work of the United States Geological Surve}^ on Susquehanna River 
by engineers and others who are promoting power schemes in the 
lower portion of the river, and it was to obtain varjang data that 
the late George S. Morison, engineer for the McCalls Ferrj^ project, 
established a gaging station at that point. 

As stated on page 130, the McCalls Ferry station was established 
in May, 1902, and during the following year 35 discharge measure- 
ments were made at stages which ranged between the highest and 
lowest gage heights during this period. These measurements were 
taken with great care, vertical velocity curves being used in most 
cases. From the measurements a rating curve and table was pre- 
pared, by which, in connection with the daily gage heights, botli the 
dail}^ and the monthly discharges of the river were computed, as 
shown on pages 137-139. 

On comparing the monthly discharges at McCalls Ferry from June 
1, 1902, to December 31, 1904, as ^tained by Mr. Morison's engineers, 
with those obtained by the United States Geological Survey at Harris- 
burg, as shown in the table on page 183, it is found that the mean 
monthly discharge is approximately between 7 and 25 per cent greater 
at McCalls than at Harrisburg. This difference is what would be 
expected, as the drainage area at McCalls Ferry is 11.4 per cent greater 
than that at Harrisburg. 

It is thus seen that the methods of stream measurement used by 
the Geological Survey give results which agree with those obtained by 
private engineers, whose work is generallj^ carried on in greater detail 
and at much greater cost. 

An inspection of the discharge curves shows that almost all of the 
individual measurements plot nearly on the curve, very few of them 
varying from it by more than 3 per cent. This fact, while it does not 
prove their accuracy, indicates that the measurements were carefully 
made and that the results are consistent.

184 HYDROGRAPHY OF SUSQUEHANNA BASIN. Fxh. 109. 

Vl^in ICAL A ELOCriY M15ASrilEMF.NTS. 

The standard with Avliich all velocity determinations in stream- 
measurement work are compared is the mean velocity obtained by 
the vertical velocity method. This method consists in taking, in a 
vertical line, a series of velocity determinations, which when plotted 
with depths as ordinates and velocities as abscissae give the basis for 
the construction of a velocit}'' curve along the vertical in question. 
This curve shows the variation in velocity from the surface to the 
bottom of the stream, and from it the mean velocity for the vertical 
can be determined by dividing the area included within the curve by 
the depth. From these curves not only the depth at which the mean 
velocity occurs can be found, but also coefficients for reducing to 
the mean the velocities found at the top, bottom, or at other points. 

In the work in the Susquehanna drainage area three series of 
vertical velocity measurements have been made, as follows: At 
McCalls Ferry, Pa.; at Binghamton, N. Y., and at Harrisburg, Pa. 

The series at McCalls Ferry, Pa., was made during the years 1902 
and 1903 by Messrs. Boyd Ehle and R. H. Anderson and consisted of 
73 determinations at the Duncans Run section and 104 measurements 
at the cable section. The depths at the first section va^-ied from 3 to 
30 feet and the mean velocities from 1.2 to 5.8 feet per second. At the 
second section the depths ranged from 3 to 36 feet and the mean 
velocities from 1.2 to 9.7 feet per second. These great depths and 
the high velocities at which these measurements were made make 
them bj^ far the most interesting series of the kind that have been 
made. 

The bed of the stream at both of these points is very irregular and 
is made up mostly of solid rock, strewn with large bowlders, as shown 
in PI. I, B, thus making the velocities near the bottom hard to 
determine. v 

The secondary guy cable witli\ which the station is equipped, as 
noted on page 131 and shown on PI. IX, A, enabled the observer 
to hold the meter at a depth which it is very difficult to reach under 
ordinarj^ conditions. 

The results of the measurements have been tabulated and are given 
in the tables on pages 185-187, and the platted curves are shown in 
Pis. XX to XXVI, inclusive. 

A study of these tables shows that in order to draw any conclusions 
from the results the individual determinations must be grouped, in 
order to bring together those which were taken under the same con- 
ditions. The grouping for the Duncans Run series was made accord- 
ing to depth as follows: Group 1, 4 to 10 feet; group 2, 10 to 20 feet; 
group 3, 20 to 30 feet, and those for the cable station according to 
the distance from the initial point. 

Rejecting disturbed and discordant observations, the averages from 
these groups give the results shown in the table on page 188.

From the above table we find, first, that the depth of the thread of 
mean velocity ranges from about 68 to 72 per cent of the total depth, 
and that holding the meter at 0.6 depth gives a result about 5 per 
cent too large; second, that the coefQcient for reducing top velocity 
to mean velocity is practically 92 per cent; third, that the coefficient 
for reducing the mean of the top and bottom velocities to mean veloc- 
ity ranges from 106 to 118 per cent. The discordance here is due to 
the roughness of bed, which reduces the bottom velocity to a minimum.

An examination of the above table shoAvs, first, that the thread of 
mean velocity varies between about 63 and 80 per cent of the total 
depth, and that holding the meter at 0.6 depth gives a result between 
and 6 per cent too large, with an average of about 3 per cent. Sec- 
ond, that the coefficient for reducing top to mean velocity ranges 
from about 85 to 93 per cent, with a mean of 90 per cent.

VERTICAL VELOCITY MEASUREMENTS. 



189 



From Jul3^ 1, 1901, ft) August 15, 1902, Mr. E. C. Murphy made a 
special study of the accuracy of curreut-meter work and the laws of 
flowing water, on Chenango and Susquehanna rivers, at Binghamton, 
IST. Y. A detailed account of these studies can be found in Water- 
Sujjplj^ and Irrigation Paper No. 95, from which paper the data used 
in the following are taken. 

I'igs. 1 and 5 show contours of the bed and position of the piers 
and abutments at the two measuring stations. The Chenango River 




Fig. 4.— Contour of bottom of Chenango River at Court Street Bridge, Binghamton, N. Y. 

station is at Court Street Bridge, Binghamton, where the observa- 
tions Avere taken. The channel there is straight for about 1,000 feet 
on each side of the station, has a width of about 300 feet at low water 
and 340 feet at high water, and is broken by three piers. The bed is 
gravel and cobbles, with large rough stones around the piers. The 
bed is seen to be irregular in shape, as well as rough, but is perma- 
nent. The station is about 2,500 feet from Susquehanna River, and 
is subject to backwater at certain stages. Although the channel is

broken by three piers, the bridge projects over the piers on each side, 
so that the section of measurement is continnoiis.

above and below the station, has a width of about 300 feet at low 
water {.nd about 450 feet at high water, broken by 3 piers. The bed 
is of gravel and cobbles, with large irregular-shaped-rock filling 
around the piers. The velocity is rather high, especially at the higher 
stages. About 900 feet above the station is a dam whose height is about 
6 feet. 

The methods of work and computations at each station were as fol- 
lows: The vertical velocity curve observations consisted in measur- 
ing velocity at from three to five points in each of the verticals, the 
lowest point being one-half foot above the bed, and the highest 1 foot 
below the surface. Each observation covered four periods of 25 sec- 
onds each. The velocities computed from these observations were 
plotted on section paper, and a smooth curve was drawn among these 
called the velocity curve. These points gave, as a rule, a well-defined 
curve, except near the bottom, where the bed was rough. 

The curves for each vertical were grouped according to gage height, 
so that the range for each group was not greater than 1 foot. A mean 
vertical velocit}' curve was then drawn for each group. In making 
these mean curves the means of the velocity at the surface and at each 
two-tenths depth of the original curves were used. The resulting 
mean curves are shown in figs. 6, 7, 8, and 9, and the deductions from 
these are given in the tables headed " Vertical Velocity Measurements 
on Susquehanna River at Binghamton, N. Y.," and "Vertical 
Velocity Curves on Chenango River at Binghamton, N, Y." 

In the tables, top velocity means velocity one-half foot below the 
surface, and bottom velocity means velocity one-half foot above ' the 
bed. Columns 9, 10, and 11 give the mean velocities in each vertical, 
as obtained by three methods, and columns 12, 13, and 14 the coeffi- 
cients for reducing velocities obtained by either of these methods to 
mean velocity as obtained from the vertical velocity carves,

196 HYDKOGRAPHY OF STJSQUEHAlSriSrA BASTlSr. [no. ini). 

From the curves and table for Chenango River it is seen tliat the 
value of the coefficient for reducing velocity obtained by the six- 
tenths-depth method varies from 0.93 to 1.03, the mean being 0.984. 
The coefficient for reducing velocity obtained by the top and bottom 
method to that obtained from the vertical velocity curve varies from 
0.96 to 1.13, the mean being 1.041, the error of this method increas- 
ing as the depth increases. The coefficient for reducing velocitj" 
obtained bj' the third method to mean velocity obtained from the ver- 
tical velocity curve varies from 0.96 to 1.03, the mean being 0.996. 

From the curves and table for Susquehanna River it is seen that 
the coefficient for reducing velocity at six-tenths depth to mean veloc- 
ity obtained from vertical velocity curves varies from 0.95 to 1.06, 
the mean being 0.992. The coefficient for reducing velocity bj^ the 
top and bottom method varies from 1 to 1.17, the mean being 1.068. 
The coefficient for reducing velocity obtained by the third method to 
mean velocity varies from 0.99 to 1.03, the mean being 1.005. 

It is seen from the result in these tables: (1) That the third method 
of obtaining mean velocity b}^ observing velocity one-half foot above 
the bed and one-half foot beneath the surface and at mid dexJth gives 
results agreeing very closely with that obtained from vertical velocity 
curves if the bed is smooth; (2) that results obtained by the top and 
bottom method agree quite closely with those obtained from vertical 
velocity curves if the depth is small and bed smooth, and that the 
error by this method increases as the depth increases; (3) that 
velocities obtained by the six - tenths - depth method are somewhat 
larger than those obtained from vertical velocitj* curves if the average 
depth is greater than about 4 feet. 

The series of vertical velocity measurements made at Harrisburg 
were taken on November 2, 1903. They consisted of 20 measure- 
ments at depths ranging from 3 to 8 feet and mean velocity varjing 
from 1.5 to 2.6 feet per second/X The results of these measurements 
are shown in the following table and by the curves on PI. XXVI.

From the.se observations at Harrisburg we find, first, that the depth 
of the thread of mean velocity ranges from 51 to 72 per cent of the 
total depth and that the mean is 61 per cent. The error, therefore, 
introduced by holding the meter at 0.6 depth is only about 1 per cent. 
Second, the mean coefficient found for reducing top and bottom veloci- 
ties to mean velocities is 1.08. Third, the coefficient for reducing 
velocities by the integration method to mean velocity is 0. 98. Fourth, 
the coefficient for reducing toi3 velocity to mean velocity is 0.85.

HYDROGRAPHY OF SUSQUEHANNA BASTN. 



[xo. 100. 



All iuterstiidy of these various series of vertical velocity measure- 
ments shows that at these stations for depths iiji to about 10 feet and 
velocities not over 5 feet per second the depth of the thread of mean 
velocity is practically 60 per cent of the total depth, while for depths 
over 10 feet and velocities over 5 feet per second the depth of the 
thread of mean velocity becomes greater, averaging about 70 per cent 
of the total depth. 

The coefficient for reducing top velocities to mean velocity for 
depths under 10 feet and velocities under 5 feet is about 0.85, while 
for greater depths and velocities it increases to a maximum of about 
0.92. 

The top and bottom velocities invariably give too small results, 
depending upon the roughness of the bed. 

Furthermore, it is found that although the depth of the thread of 
mean velocity may vary between 50 and 80 per cent of the total depth, 
the error caused by holding the meter at 60 per cent of the depth 
does not exceed 5 or 6 per cent, which is within the limits of the accu- 
racy one can expect in stream-measurement work. 

The following table gives a summary of the results of the various 
series of vertical velocitj^ measurements in the Susqehanna drainage:

WATER POWER. 

GENERAL DISCUSSION. 

In marked contrast to the New England streams, the power 
resources of the Susquehanna River basin, one of the largest drain- 
ing into the Atlantic Ocean, are. little developed. 

As shown by the tables on pages 204, 205, taken from schedules fur- 
nished by the manufacturers' division of the Twelfth Census, 1 900, a 
maximum of 10,375 horsepower is utilized in the portion of the 
drainage area in New York and 38,812 horsepower in Pennsjdvania. 
This makes a total of less than 50,000 horsepower — an amount which, 
according to the estimates of various engineers, can be developed at 
any of several points on the lower river. By far the greater part of 
this is developed intermittently uj)on the smaller tributary streams 
by mills of from 20 to 50 horsepower. Pis. XXVIII and XXIX show 
the profile of Susquehanna River and its principal tributaries. These 
profiles are made up from data obtained from the army engineers, the 
report of the Tenth Census, Vol. XVI, and from levels furnished hy 
private engineers, as shown in the tables on pages 207-210. 

Over the greater portion of the river above Harrisburg the fall per 
mile is from 1 to 2 feet, while below Harrisburg the fall increases to 
between 5 and 8 feet, and it is here that the greatest opportunities 
for large power developments exist. The only point on the entire 
river at which this fall is now being utilized to anj^ great extent is at 
York Haven, where a paper mill uses 2,000 horsepower, and a large 
electric-power plant in course of construction will soon use 10,000 or 
20,000 more. 

Mr. W. F. Bay Stewart, of York, Pa., describes the York Haven 
Power Plant, as follows : 

The York Haven Water and Power Company's plant is located at the foot of 
the Conewago Falls on the Susquehanna River, ten miles from York and sixteen 
miles below Harrisburg. The natural fall at this point is about 23 feet in about 
three-quarters of a mile. The method of utilizing this fall is by building a wing 
dam out into the river above the falls and turning the greater portion of the flow 
by means of this wing dam within a retaining wall 3,500 feet long, constructed of 
masonry. This wall is built along the river shore just above low water. The 
wall is 16 feet high at the upper end and 33 feet high at the lower end, it is 6 feet 
wide on top all the way, and is built vertical on the inside and with a batter on 
the outside toward the river. The width of the foundation increases with the 
height of the wall, so that at the lower end it is about 22 to 24 feet in width. It 
is built of rubble masonry laid in cement. 

The power house begins at the lower end of this wall, and is about 50 feet wide 
and 480 feet long. It contains twenty full-sized chambers and one smaller cham- 
ber. The design is to install in each of these chambers two 600-horsepower 
water wheels, and to connect the shafts of these water wheels by means of bev- 
eled gears at their top with the shaft of a 750-kilowatt generator, which runs 
horizontally and which is intended to develop at least 1,000 horsepower. To 



200 HYDKOGRAPHY OF SUSQUEHANNA BASIN, [no. 109. 

equip the plant will require forty OOO-horsepower water wheels and twenty 
generators. In addition to this, in the smaller chamber there will be installed 
two 300-horsepower water wheels which drive two exciters, duplicates, either 
one of which is capable of exciting the whole plant. This building up to a 
height of 34 feet is of the same class of masonry as the retaining wall, and these 
chambers for water wheels are practically openings in an otherwise solid mass 
of masonry 480 feet long by 50 feet wide and 34 feet high. On top of this 
foundation is a brick building, one portion of which is two story and the remain- 
ing, one story. In the two-story part the switch boards and controlling devices 
are located. At the lower end of this biTilding and at right angles to it another 
wall is constructed the same height as the high part of the retaining wall and 
about 170 feet long. This wall then extends in an irregular form around the 
buildings of the York Haven Paper Company's plant to the main land. On the 
angle of this wall is constructed a tranformer house sufficient to receive the ma- 
chinery for transforming all the current generated in the generating plant. The 
current is developed at 2,400 volts and stepped up to 24,000 volts in this trans- 
former house and is transmitted at this voltage to points of consumption. The 
company has built a transmission line capable of transmitting 6,000 horsepower 
from York Haven to York, where another transformer house has been built capa- 
ble of transforming 24,000 volt current down to 2,200 volts, at which voltage it 
will be delivered to customers. It is the purpose of the company to build a like 
transmission line to Harrisburg, with a like transformer house at that city, and, 
possibly, also to Lancaster, Pa. , which is about 20 miles from the plant. The 
machinery installed and to be installed in this plant is capable of an overload 
of 25 per cent, thus increasing the capacity to 25,000 horsepower, and of course 
it could be more largely increased by raising the head. 

Between York Haven and the mouth of the river there is a fall of 
about 270 feet. The mean annual discharge at York Haven from 
1891 to 1904, inclusive, is about 40,000 second-feet. By applying the 
rule that 11 second-feet of water falling 1 foot equals a horsepower 
with 80 per cent efficiency it is seen that between York Haven and 
the outlet of the river there about one million horsepower running 
to waste, though several neighboring cities would aiford an eager 
market for all that could be developed. There are, of course, several 
obstacles in the way of development, perhaps the most serious of 
which would be the occasional ice freshets and gorges, making sub- 
stantial protective works necessary and reducing or obliterating the 
available head. Between the narrows above McCalls Ferry and Port 
Deposit, however, the ice passes down through either a deep or a 
broad channel, with no tendencj^ to gorge and seldom doing damage. 
At present there are several individuals and companies who are pro- 
moting power schemes on the lower river, and a large plant at York 
Haven has recently been completed. 

Mr. H. F. Labelle, who spent several years in the study of the 
power possibilities of the lower Susquehanna, states the following in 
regard to the i)ower developments on the lower Susquehanna River: 

The bed of the stream from Columbia to Port Deposit is for the most part 
very wide, varying from 3,500 feet to about 2^ miles opposite Washingtonboro. 
There are, however, a few "narrows," as at Conowingo and McCalls Ferry. The 
stream being wide and rapid, it naturally follows that at low water it is verj 
shallow and can be forded in many places. The water in the narrows is, how- 



Tn^r^^.] watee power. 201 

ever, very deep. At Conowingo Bridge, on the west side, there is a narrow chan- 
nel over one-half mile long in which depths of 75 feet have been found. At 
McCalls Ferry, where the river narrows to about 300 feet, the depth is also con- 
siderable. These deep channels are also met here and there on the wider parts of 
the river-^namely, between Turkey Hill and Star Rock station, on the east side, 
where depths of over 90 feet have been found. 

The Susquehanna and Tide-water canal skirts the west side of the river from 
Wrightsville to Havre de Grace. Before the building of the Philadelphia, Balti- 
more and Washington Railroad and the Frederick Branch of the Pennsylvania 
Railroad this canal had a brisk carrying trade, chiefly in coal from the anthra- 
cite regions. The flood of June, 1889, wrecked the canal in many places. The 
cost of repairs was very high, and the canal continued in operation until May, 
1894, when another flood caused considerable damage to the property. Since that 
time it has been practically out of operation. After changing hands several 
times, it was finally bought by the Susquehanna Electric Power Company, of 
Baltimore. This company is about to begin the construction of their first plant, 
below Peach Bottom. The Frederick Branch of the Pennsylvania Railroad runs 
on the west side of the river from Columbia to Perry ville, where it connects with 
the main line of the Philadelphia, Baltimore and Washington Railroad. 

The minimum discharge of the river at Shures Landing can be taken safely at 
6,000 second-feet. This would give a minimum gross power to be developed from 
Columbia to tide water of 103,000 horsepower. The proposed plants, however, 
have been designed for a supply of 10.000 second-feet, which is available most of 
the time. 

This would give a possible power of about 255.000 horsepower. This available 
power can almost be totally utilized, and the writer knows of projects on the 
river aggregating over 185,000 horsepower. 

The power available on the Susquehanna has at its disposal a much better 
market than any other in the United States, not barring Niagara Falls. Balti- 
more is a little more than 40 miles from the half of the minimum i)ower and Phil- 
adelphia is within 65 miles of the two lower plants, taking on the way Wilming- 
ton, with its heavy power consumption. 

The tipper plants are within easy reach of Lancaster, York, Harrisburg, Read- 
ing, and other manufacturing centers. Eastern Pennsylvania, with its great 
manufacturing activity, will surely avail itself of whatever amount of power can 
be developed on the river, and towns like Havre de Grace (10 miles below Shures 
Landing) , located on two of the large trunk lines between the North and the 
South and also at the head of Chesapeake Bay, can be transformed by cheap 
power into manufacturing centers of no mean importance. 

There is no doubt that with the help of steam plants — and there are many 
already established in the larger cities of the district— 400,000 horsepower could be 
developed on the river below Columbia and find a ready and remunerative market. 

Starting from tide water the principal plants projected are as follows: (1) Con- 
owingo plant, 25,000 to 35,000 horsepower; (2) the PeachBottom plant, 40,000 horse- 
power; (3) the Fites-Eddy plant, 40,000 horsepower; (4) the York Furnace, Mc- 
Calls Ferry plant. 45,000 horsepower; (5) the Turkey Hill plant, 30,000 horsepower. 

There is about 9 feet fall available below the Conowingo works, but it is 
believed that the conditious would not make it advisable to develop any power at 
that point. 

At Conowingo the power house is located a short distance above Shures Landing. 
The building extends for a distance of about 500 feet, square across the stream 
from the west shore. The original development is to be of 25,000 horsepower, but 
provision is made in the power house for the development of 10,000 additional 
horsepower. From the river end of the power house the dam extends upstream 



202 HYDEOGRAPHY OF SUSQUEHANNA BASIN. [no. 109. 

a distance of 1,200 feet, the crest lieing at an elevation of 50.5 feet. The dam then 
turns toward the f(jot of McDowells Island, 800 feet away; thence it follows the 
center of McDowells Island for 3,600 feet to its head, and thence it goes diagonally 
to the east shore, a distance of 2,600 feet. The last 7,000 feet have their crest at 
an elevation of 43 feet, except 200 feet close to the high part of the dam, where a 
spillway for ice has been located, its crest being at an elevation of 41 feet. A 
needle dam will close this spillway at ordinary stages. The river above 
McDowells Island is over 3,000 feet wide and the dam forms a pool over 4 miles 
long. It has a sufficient rollway to pass the highest known floods without 
endangering the riparian property above it. The high part of the dam and the 
McDowells Island section are 8 feet wide on the crest. The remainder of the dam 
has a crest 12 feet wide. The whole dam will be of rubble, with ashlar facing on 
the downstream side. Borings have shown that a continuoiis rock bottom will 
be obtained on McDowells Island at an average depth of 11 feet. The generating 
plant will probably be divided into 1 ,250 kilowatt units. The tiirbines will be 
vertical, with draft tube. One pair of turbines will serve each dynamo, the con- 
nection between turbines and horizontal shaft of dynamo being made by two 
crown wheels engaging bevel gears on this shaft. 

The working head will be 34 feet at low water and 30 feet at ordinary stages. 

The Turkey Hill plant is located between Turkey Hill and Safe Harbor, on the 
east side of the river. At Turkey Hill the river is about 1 mile wide, and a low 
diverting dam about 5 feet high will form a large pond above it. This pond 
extends to Columbia, a distance of 5 miles, and its width varies between 1 and 2| 
miles. The head and tail race canals are formed by an embankment paralleling 
the railroad track and forming a canal varying from 190 to 250 feet in width at 
the bottom. This embankment is about 3 miles long. It is composed of a river 
wall in cement battering li inch per foot on the river side and 2^ inches on the 
back. Next to this is the loose rock embankment proper, 40 wide on top and 
sloping 1 to 1 on the power-canal side. This mode of construction will meet the 
impact of the ice and prevent it from overtopping the embankment. At the main 
dam, and close to the head works, there will be a raft chute and a raft channel 
leading from it and close to the embankment on the river side. The average 
working head will be 30 feet, and the power house will be located at Star Rock. 

DURATION OF THE STAGtES OP THE LOWER SUSQUEHANNA. 

In order to show the mean conditions and the duration of flow which 
have existed on tlie lower Susqnehanna River during tlie last twelve 
years — 1891 to 1902, inclusive — the curves in PI. XXVII have been con- 
structed. The dotted-line curve is iDlotted with gage heights as ordin- 
ates, and with the number of days during the mean year on which the 
stage of the river was less than the given gage height as abscisspe. 
The full-line curve shows the number of days during the mean 
year when the discharge was below ginj given amount. In the prepa- 
ration of these curves the Harrisburg gage heights for each j^ear, as 
shown on pages 108 to 114, were tabulated according to magnitude. 
The number of days during the year when the water stood at each gage 
height were then tabulated, and from these the number of daj^'s during 
the year when the river was lower than the various gage heights was 
determined. The curves were constructed from the mean of these j^early 
tables, and in the case of the full-line curve the discharges as given 
in the rating table on page 115 were substituted for the gage heights.

To use the two curves in con junction with each othei', enter the 
diagram with a certain gage heiglit, find where it intersects the gage- 
lieiglit curve, then follow the ordinate of this intersection until it cuts 
the discharge curve, and the discharge for that particular gage height 
is found on the right side of the diagram. 

Assuming that the discharges at the various points in this portion of 
the river vary in proportion to the drainage area above, one can readily 
determine by the use of the curves the conditions which may reason- 
ablj'- be expected at any point below Harrisburg. For example, sup- 
pose one wishes to know how many days during the mean year the 
discharge will be less than 5,500 second-feet at the Pennsylvania- 
Maryland line, where the drainage area is 27,150 square miles, or 13 
per cent more than at Harrisburg. As the drainage area at Ilarris- 
burg is 88.6 per cent of that at the State line, 5,500 second-feet would 
correspond to a discharge of 4,870 second-feet at Harrisburg. From 
the full-line curve on PI. XXVII we find that for twenty days during the 
mean year the discharge is less than 4,870 second-feet at Harrisburg, 
or 5,500 second- feet at the Maryland-Pennsylvania line. 

By applying the following simple rule for horsepower it is possible 
to determine the probable power which could be -developed during a 
mean year at any point in the lower Susquehanna : 

Rule : Horsepower on the turbine shaft equals the discharge in sec- 
ond-feet multiplied by the fall divided by 11. This is based upon an 
assumption of 80 per cent efficiency for the turbines. 

Applying this to the above example, we find that for three hundred 
and forty-five daj^s during the mean year 500 horsepower for 80 per 
cent efficiency can be developed for each foot fall at the Maryland- 
Pennsylvania line. 

RULES FOR ESTIMATING DISCHARGE. 

The approximate mean monthly discharge in second-feet for any 
stream in the Susquehanna drainage basin, may be determined in 
either of two ways — 

First. Its drainage area in square miles can be taken from the 
table on page 15, or measured on a map, and multiplied by the 
monthly run-off in second-feet per square mile given in the tables of 
the nearest gaging station. 

Second. The monthly rainfall in inches for the district, as deter- 
mined from the tables on pages 161 to 171, can be multiplied by the 
per cent of run-off for that month at the nearest of the three gaging 
stations — Wilkesbarre, Williamsport, or Harrisburg — giving the total 
monthly run-off in inches. This result multiplied by one of the fol- 
lowing coefficients gives the mean monthly run-off in second-feet per 
square mile : 

For montli of 28 days 0. 9603 

For month of 30 days . 8963 

For month of 31 days. .' .8674

[NO. 109. 



The drainage area in square miles may be found as before, and 
if multiplied by the above product will give the mean discharge of 
the stream for that month in second-feet. 

The horsepower may then be computed by the rule on page 203.
